Usage Guidelines

Usage Scenario

To allow a DHCP relay agent to request a DHCP server to release a DHCP client IP address so that the client can log out, run the dhcp relay release command. If a DHCP server is specified, the DHCP relay agent sends a DHCP Release message only to the specified DHCP server.

Configuration Impact

If the DHCP server's IP address is not specified, the DHCP relay agent sends Release packets to all DHCP servers.

Example

# Configure a DHCP relay agent to send Release packets to the DHCP server with the IP address of 10.110.91.174, requesting the IP address 192.168.2.25 for the DHCP client with the MAC address of 00e0-fc34-2000.
